A proportional solenoid-operated, two-way, poppet-type, normally closed, screw-in hydraulic cartridge valve for low-leakage blocking and load-holding applications
When de-energized, the SP08-20A acts as a check valve, allowing flow from 1 to 2, and blocking flow from 2 to 1. When energized, the 2 to 1 flow path is opened. Flow is proportional to current applied to the coil. Flow varies with manual override.
Note: If low voltage is expected on the machine, 12 or 24 volt systems will require the use of 10 volt or 20 volt coils respectively. See “SP Valves and Coil Operating Parameters,” page 2.002.1.
• Industry-common cavity.
